Thingiverse item 6397468 is a single-piece B♭ bugle utilizing a trumpet mouthpiece, created by John Methvin-Terry of WhateverWorks in 2023. Wall thickness was [supposedly] increased in Blender.
Bugle is similar to the M1894 “trench” bugle, triple-wound tighter than the glancingly-similar M1855 British “duty” bugle. The “trench” designation was colloquial, though the compact size suits large trench coat pockets.
This design comes from an outside source and is being evaluated through print outsourcing to Materialise NV of Belgium. Design is provided here for exposure and non-commercial purposes, and should be considered experimental.
